| 摘 要： | 在中子感生瞬发γ射线法分析煤炭元素含量中,用蒙特卡罗程序模拟出C,H和O的特征γ射线计数与煤层厚度之间的关系.结果表明:煤层的厚度为63,116和51 mm,这3种元素的特征γ射线计数分别达到最大值.在试验装置中,煤层的厚度为80 mm,对C,H和O测量结果的绝对误差分别为0.41%,0.16%和0.66%,低于煤层其...

| Abstract: | In analyzing the element contents in coal by NIPGA(Neutron Induced Prompt Gamma-ray Analysis),in order to increase the precision,we used MCNP(Monte Carlo N-Particle Transport code) to simulate the relationship between the count of the characteristic gamma-rays and the thickness of coal.If the thickness of coal is 63mm,116mm and 51mm,the gamma-rays' counts of carbon,hydrogen and oxygen achieve maximum,respectively.In the experimental setup,the thickness of coal is 80mm.The mean absolute errors of carbon,hydr... |
